How can you ensure an impartial and independent ISMS audit and review?

1 Choose a competent and qualified audit and review team

The first step is to select a team of auditors and reviewers who have the appropriate skills, knowledge, and experience to conduct the ISMS audit and review. They should also be familiar with the relevant standards, regulations, and best practices for information security in the airport industry. Moreover, they should be able to demonstrate their objectivity and integrity by avoiding any conflicts of interest, bias, or undue influence from internal or external parties.

3 Plan and prepare the audit and review activities

The third step is to plan and prepare the audit and review activities, which should be consistent with the scope and criteria of the audit and review. You should develop a detailed audit and review plan that outlines the roles and responsibilities, timelines, resources, methods, and tools for the audit and review. You should also provide the audit and review team with the necessary information and documentation to support their work, such as your ISMS manual, risk assessment, policies, procedures, records, and reports.

5 Report and follow up on the audit and review results

The final step is to report and follow up on the audit and review results, which should be accurate, complete, and timely. You should ensure that the audit and review team prepares a comprehensive audit and review report that summarizes the objectives, scope, criteria, methods, findings, conclusions, and recommendations of the audit and review. You should also ensure that the audit and review report is reviewed and approved by the appropriate authorities, and that it is distributed to the relevant stakeholders. Moreover, you should ensure that the audit and review report is used as a basis for improving your ISMS, and that you monitor and verify the implementation of any corrective or preventive actions.
